IMPROVED APPARATUS FOR GENERATING STEAM.

Specification forming part of Letters Patent No. 58,727, dated October 9, 1866.

To all whom it may concern:

Be it known that I, ELIAs S. HUTonINsoN, of the city and county of Baltimore, and State of Maryland, have made new and useful Improvements in the Application of Carbureters to Steam-Generators, 85c. and I do hereby declare the following to be a full, clear, and exatt description of the nature, construe tion, and operation of the same, sufficient to enable one skilled in the art to which they are allied to construct and use the same, reference being bad to the accompanying draw ings, in which my improvement is shown as applied to a locomotive steam-engine, and in which- Figure 1 is a vertical and longitudinal section 011 the line a- .r, Fig. 2. Fig. 2 is a longitudinal section of the same on the irregular line y y, Fig. 1. Fig. 3 is a vertical transverse section on the line 2 2, Fig. 1.

The invention consists in combining with the moving parts of the machinery an air- 1 come general in many of the arts, and adapted to many mechanical uses, I have sought for a plan of making it available for generating steam for a motor. For this purposel attach an air-pump, or some other air-forcing apparatus, to some moving part of the machinery, by means of which air is driven through a carbureter for the supply of inflammable gas as fuel for the use of the boiler, or for other calorific or photic uses.

The piston air-pump is shown as an illustration, but any other form of air-forciu g apparatus may be employed.

In the drawings, A isthe boiler, and B B B vertical tubes therein. 0 is the steam-jacket around the boiler proper, the fire-chamber, and steam-space. I) is the steamdome. The boiler and engine are mounted on a frame, F, and wheels Gr.

H is the cylinder; Q, the piston-rod; P, the

slides; N, the-pump-rod; I, the force-pumps, by which air is injected through pipes J into the chamber K, from which it passes, by the pipe B, into the chamber L, in which the hydrocarbon fluid is contained. The ordinary atmospheric air, which passes through the fluid in L, becomes carbureted andinflammable, and passes by the pipe M to the burners, which are situated under the boiler in any required position, number, or size. I have shown them as each underneath a vertical flue, which has a central spherical enlargement, and discharging the heated and uninfiammable gases resulting from combustion into the chamber 0, and thence, by the chimney E, into the open air.

A safetyvalve, O, on the air-chamber K provides'egress for the air in said chamber when it has attained a certain pressure.

I have shown the application of my inn provement to a locomotive-engine; butI do not limit myself to any particular form of boiler, engine, air-pum p, carburcter, or burner.

The carbureter and pump may be consolidated in some manner. I speak of them by their functions, not as necessarily detached portions. The essential functions are the engine, air-forcing apparatus, carburetor, and boiler, with or without a compressed-air chamher, and the conduction of inflammable gas to other parts of the apparatus or structure for calorific or photic purposes.

A pipe from the carbureter may conduct the carbureted air to other locations in connection with the engine, such as the requisite lighting and heating arrangements of the train of cars,or the buildings in connection with the engine.

Having described my invention, what I claim therein as new, and desire to secure by Letters Patent, is

1. The combination of an air-forcing apparatus and carburetor with the engine and the boiler, for the purpose described.

2. In combination with the engine, air-forcin g apparatus, carbureter, and boiler, the chamher for reserve of compressed air, as and for the purpose described.

3. The boiler-tubes,constructed withaspherical or equivalent enlargement, as and for the purpose described.
